A numerical approach is presented to study the crystallographic orientation-dependent performance of 445nm InGaN/GaN quantum well (QW) Blue Laser by solving a six-band k.p Hamiltonian for wurtzite crystal using finite difference method. Euler's rotation technique is used to modify the wave vector and Hamiltonian matrix in conventional (0001) crystal orientation. It is found that there is a substantial...
In this paper, the crystal orientation-dependent electronic and optical performance of a compressively strained quantum well (QW) blue-violet Vertical Cavity Surface Emitting Laser (VCSEL) is numerically simulated using MATLAB. It is found that there is a strong correlation between the crystal orientation and the energy band dispersion and hence the optical emission spectrum of the laser. The peak...
A numerical approach is presented to calculate crystal orientation-dependent effective mass of heavy hole, light hole and spin-orbit split-off hole of III–V semiconductors (GaAs, InAs, InP, GaSb, and InSb etc.) at Gamma-point by envelope approximation using k.p method. Unitary transformation is used to modify the wave vector and eight-band k.p Hamiltonian is applied in conventional (100) crystal orientation...
In this paper, the crystallographic orientation-dependent performances of 635nm red quantum well (QW) laser are numerically studied. The electronic and optical characteristics of the laser are investigated by solving time independent Schrodinger equation using finite difference method. The results are obtained in (001), (101), ((111), (113), and (211) orientations and found that there is a substantial...
A numerical approach is introduced to study the optical properties of compressively strained InGaAs/GaAs quantum well (QW) architecture considering the piezoelectric (PZ) effect by solving one dimensional Schrödinger equation using finite difference method. Unitary transformation is used to modify the wave vector and strain matrix in conventional [100] crystal orientation. The simulation is carried...
